Remove the cord retainer that secures the power cord
to the failed power supply and disconnect the power cord from the
firewall.
Grasp the handle on the failed power supply and then
simultaneously press the release lever to the left and pull the
power supply outward to remove it.
Remove the replacement power supply from the packaging
and slide it into the empty power supply slot. Push the power supply
all the way in until the release lever clicks and secures the power
supply.
Connect the AC or DC power cable(s) to the power supply input and secure it to
the power supply using the cord retainer. Once the power supply powers on, the
input and output LEDs on the power supply turn green. Similarly, the PWR LED and
the power supply LED (PWR 1 or PWR 2) on the front of the firewall turn
green.
